Description

This is a PHP script that records data from Internet of Things (IoT) devices in a CSV spreadsheet that can be opened from Excel. If you also need a web view for the log, check the CSV Viewer for Web Browsers.

Objectives

Create a Pivot table that displays text data or number values that are not summarized (count, sum, etc...). This solution does not require macros or long search/replace functions, just the Microsoft Power Query tool that comes with Excel 2016 or can be installed for free as an add-on in previous versions.
